Abstract

Copper is one of the key heavy metals that pollute environment and constitute a serious threat to the health of humans and ecosystems. Copper may enter the aquatic environment in both soluble and nanoparticle form. It was previously found in a series of studies that nanoparticles, including those of several metal oxides, exercise both negative and positive effects on the higher plants which makes necessary further research on the interaction between metal oxide nanoparticles and plants. Interactions between aquatic plants and copper-containing nanoparticles were not sufficiently studied. The goal of this study was to contribute to the investigation of the interactions between CuO nanoparticles and the aquatic plant Elodea canadensis under the conditions of experimental microcosms. It was found that CuO nanoparticles demonstrated some phytotoxicity to Elodea canadensis. After the incubation of Elodea canadensis in the aquatic medium contaminated with CuO nanoparticles there was a significant increase (by two orders of magnitude) of the concentration of copper in the biomass of the plants.

Description

The Russian Journal of General Chemistry (Zhurnal obshchei khimii) is a major journal in the field of scientific chemistry, with a unique pedigree: it is the successor to Russia's first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (The Journal of the Russian Chemical Society), founded in 1869. Today, the journal focuses on new achievements and long-term results in many related disciplines in chemistry, includi � show all
